Analog Controlled Solid State Relay

May 14, 2008
Carlo Gavazzi has just released the newest addition to the SOLITRON family of solid-state relays: the RJ1P Series, a microprocessor controlled device with analog input and proportional output capabilities. The RJ1P Series is a single package solution that is capable of switching single phase 230, 480 or 600 VAC, up to 50 AAC loads with 5 different operating modes, when controlled by 0-10 VDC or 4-20 mA signals. The RJ1P Series comes with an integrated heat sink and is ready for DIN rail mounting.   The RJ1P Series solid-state relay provides equipment designers with the ability to precisely control output power. 4mA or 0VDC corresponds to 0% output, linearly increasing to 100% at 20mA or 10VDC. A rotary selector stitch on the front of the device is used for selecting the preferred mode of operation, i.e. either phase angle, distributed full cycle or 3 types of burst modes (1, 3 and 10 sec.). The RJ1P Series is designed to work with analog output temperature controllers for switching a variety of applications, including heating and lighting. It comes with an integrated varistor and has extremely high surge capabilities (I2=18,000A2s).  The RJ1P is ideal for HVAC, lamp and lighting control, printing, plastic and rubber, wood and industrial heating applications and it is a solid complement to Carlo Gavazzi’s existing range of SOLITRON products, providing a flexible, single package solution that can serve several purposes.
